Periodic Table – Royal Society of Chemistry
WebThe periodic table of chemical elements, often called the periodic table, organizes all discovered chemical elements in rows (called periods) and columns (called groups) according to increasing atomic number. Scientists use the periodic table to quickly refer to information about an element, like atomic mass and chemical symbol. WebBy convention, elements are organized in the periodic table, a structure that captures important patterns in their behavior.Devised by Russian chemist Dmitri Mendeleev (1834–1907) in 1869, the table places elements into columns—groups—and rows—periods—that share certain properties.These properties determine an element’s … cgn3acsmr
